MINIMISING CARBON TRANSFER IN AN ELECTROLYTIC CELL

摘要

An electrolytic cell for reducing a metal oxide, such as titania, in a solid state is disclosed. The electrolytic cell includes an anode formed from carbon and a cathode formed at least in part from the metal oxide. The electrolytic cell also includes a membrane that is permeable to oxygen anions and is impermeable to carbon in ionic and nonionic forms positioned between the cathode and the anode to thereby prevent migration of carbon to the cathode.
